The Uniswap V3 Subgraph is an open-source project that facilitates real-time querying and indexing for Uniswap V3 data on The Graph’s decentralized network. The subgraph syncs at a specified endpoint, allowing developers to access up-to-date data and pending changes efficiently. The project employs Docker for containerization and relies on PostgreSQL for database interactions, with instructions to build and test using `yarn`. Extending support for new blockchain networks involves updating the configuration in `src/utils/chains.ts` and `networks.json`, with network parameters sourced from Uniswap and The Graph’s documentation. Deployment to Alchemy for network interaction is streamlined through a dedicated `yarn` command, ensuring scalable distribution across supported environments.
